RURGLAR 'Annr nin ALARM.

To all whom it magj'conjc'ernk- Be it known that I, Fmamncn Cannso'x, a

subject of the Kingi of Sweden, residing at Monessen, in'the county of :estmorelaud and State of Pennsylvania, have invented certain new and. useful Improvements in "Burglar and Fire Alarms, of which the following is a specification.

" This invention relates to 'a combined automatic burglar-and fire alarm designed to jgive an electric-signal in either event and embraces as a novel feature fusible means for' separat-inga pair of electric contacts "and connections abnormally operatiie to *displace .the fusible means.

One of the objects of my invention is to attain great simplicity in construction and efficiency in use and to this end my invention comprises the construction, arrange-- "zoment', and combination of parts hereinafter described, shown. in the drawings, and then mdreflparticularly defined iirthe appended:

In the drawings Figure 1 -is side eleva tionin part of a'window witlrmy alarnrattached to-thewind'owjamb Fig. '21s an end elevqfonof my alarm device looking in the directid-i of the'arrow in Fig. Fig. 3

Fig. i 4 is a side elevation, partly' in.sectionof my -.Ia-la rm mounted on a door jainb showing the door in open ,position to actuate. th'ejb'urglar Warm.

The various parts preferably lie 4!; within the area of the top of the block'and f inmvable .contart n'iember is shown at 2 which is suitably pivoted at This contact member rui'ved at Q and formed intermediate its ends with a notch Q forming a [lo-bearing for o'n 'end of the bracing and sep aratingmeans t which bears at its opposite end against a lug or upstanding projection 6. A retraetil. spring 5 secured to a stud 4 tends-to pull the movable contact. 2 into rigid contact. with the stationary contact 12.

The trip lever 9'is' composed of the port'ion flfiagainstwhich the waxenmember rests, shown-in Fig. at, anda hook portion f) to .\'l1l(l1-lS secured a flexible. member or cord 15 secured to a door 13 or either sash of a window a or c'. A stud 8 terminates in an axle 8' upon which the lever 9 is pivotally mounted. The leverb is held in norspringll fastened thereto at one'end and to a stud 10 at the other the portion 9 of the lever bearing upon tliql'aase-plate 1.

electrical connection beneath the base-plate l at. the collector 3 through the anode conductor 17, a similar connection for the contact- 12 being shown at 12 through the cathode conductor 16. The flexible member -l-l--\\'l1l(.ll engages the hook 'oflset 9 of the trip lever 9 and, being fastened-atits oppositeend toa door or window to hold the conta ts spaced, itwill be seen that when 'the-door is opened, as in Fig. 4,.the trip lever 9- will he tilted thereby ejecting the .ble or visible signal. If the sash (1 be raised, as shown in F 1g. 1, the same result \\'lll ensue.
